Summary

ASPECT is an award-winning scalable building energy management and control solution designed to allow users seamless access to their building data through standard building protocols including smart devices.

Description

The building management system suffers from an unauthenticated arbitrary file disclosure vulnerability. Input passed through the 'logFile' GET parameter via the 'logYumLookup.php' script is not properly verified before being used to download log files. This can be exploited to disclose the contents of arbitrary and sensitive files via directory traversal attacks.
